The combination of El Niño and climate change is amplifying extreme weather events globally. Heatwaves are striking regions unaccustomed to such conditions, including Europe, North America, South America, and India. Nighttime temperatures are particularly concerning, as they disrupt sleep and impair health. Wildfires are spreading rapidly, fueled by dry conditions and elevated temperatures. Scientists warn that these events are vivid examples of the risks posed by climate change, including increased wildfire probability and more frequent, severe heatwaves. The impacts are not isolated, with cascading effects on ecosystems, human health, and economic productivity.
